ELECTBOGALVANIC GENERATOR.

Specification of Letters Patent.

Patented Feb'. 25, l1913.

Application mea January 5, 1912. .serial No. 669,555,

To all whom t may concern: Be it known Vthat I, ALONZO Dow, a citizen of the United States, residing at Wooster, in the county of Wayne' and-State have invented certain new and useful Improvements in Electrogalvamc Generators, of which the Vfollowing 1sa speciication.

My invention relates to improvements in electro-galvanic generators o-r batteries, the present embodiment being well adapted for electro-therapeutic apparatus for use 1n the electro-therapeutic diiusion or lspread of electric currents throughout the diierentportions of the human'body lying between two electro-therapeutic electrodes in the treatment and cure of diseases. y

The invention relates more particularly to that class of galvanic batteries or generators which are designed to operate through direct contact with the atmosphere andpgenerate and diffuse an electric current'wheresoever desired for use, as for example, throughout the body in the electro-therapeutic treatment of disease. i

rThe primary object of the invention 1s to provide a generally improved battery. or generator of this class of exceedingly simple, cheap, and etiicient construction for the purposes above mentioned.

Referring to the drawings forming a part of this specification Figure 1,. is a perspective View of the improved generator or bat-` tery. Fig. 2, an enlarged detail view of the opposite side of the casing showing the removable head removed the casing being reversed longitudinally from the position shown in F1g.i1, the series of battery' cells being partially Withdrawn from the battery casing for the purpose of clearer illustration of the parts. Fig. 3, a detail sectional view of some of the battery cells and connections, in a separated position for the purpose of clearer illustration of thev Fig. 4, an end view of one of the' parts. y zinc or copper elements o-r electrodes of one of the battery cells. v

Similar numerals ofl reference designate like parts throughout all the figures of the drawings.

The improvedelectro-galvanic generator or appliance comprises an'open battery casinv 1, ot'suitable material such as hard rubber or the like, said casingbeing pret erably provided with slotted .openings 2, for

the free passage ofthey air into and through the battery cells hereinafter described, and

provided vwith stationary and removablev terminal heads or ends 3 and 1 respectively carrying contact Vmembers 3a and Ata, said contact members, in the present instance, being in the form of socketmembers to receive the connecting pins 5,;attached to' the conduit or conducting vcords 6.' v

The generator of battery casing, in'the present instance, is provided on opposite sides with longitudinally extending metallic plates 8 and 9, the plate 8 and subjacent portion of the casing 1, being iprovided with a series ot insulated openings 10, for thereception of one or more connecting pins 5, carried by thecords`6, as' hereinafter e plained, and the other plate 9, has a limit d movement at one end and provided with a catch or beveled lug 11, for removably holding and .securing the removable terminal head or end 4, in closed position by engagement wit-hin a similar shaped `recess in -the inner adjacent side Aof the latter.

The compound battery comprises a series of battery cells removably mounted within the generator or battery casing 1, each of said cells comprising a generating element or .electrode 12, consisting of a zinc plate, and a positive element or conducting elec'- tr0de13, of copper, said zinc and co per electrodes 12, and 13 being separated rom each other by a similarly shaped intermediateelement 14, of absorbent material such as felt cloth, or the like. l

The elements 12, 13, andpllt, comprising the cells are provided near their ends with openings 15, for the reception of insulated cords 16, such as paraiined cord or the like, said cell members being held in regularly spaced relation to each other and connected in circuit throu l1 the'medium of suitable metallic conducting member 17, in the pres-' ent instance, in the form of eyelets orrings of suitable conducting material -such as Vcopper or brass to provide for :the cumulative effect of the cells by the transmission of the electric current k,derived from the chemical' action in the battery cells it is conducted from and through'the negative and positive poles of thebattery or generator. The end cells of the series are'held out of contact-with the heads or ends 3 and 4 by means of the insulated cord heads 16a As a means for holding the series of battery cells in Aproper position within the casing 1, as well as insuring the contact at all times between the terminal battery cells and the contact members 3a and 4a as Well as in the form of a coiled spring adapted to contact with the adjacent endbattery cell in making the electro-magnetic connection, said spring member being adapted to. be compressed as the removable head member 41:, is moved into position, and held under compression when the latter is latched and held in its closed position through the medium of the catch memberl 11, carried by the mov able free end of the metallic plate 9.

When it is desired to decrease or vreduce the cumulative eli'ect of the batter cells and consequently the strength ofthe e ectric current, one of the connecting pins 5, of one of the conducting cords 6, may be inserted in one of the insulated openings 10, and downwardly between two of the subjacent battery cells in accordance with the requirements in the particular case.

From the foregoing descript-ion, taken in connection with the accompanying drawings, the operation and advantages of my inventionwill be readily understood.

Having thus described one of the embodiments' of my invention, what I claim and desire to lsecure by LettcrsPatent is,-

1. In an electr'oegalvanic generator, anv

open casing provided with terminal heads one of which is'removable, a series of Vbattery cells, insulated liexible members extending through said cells, conducting ring members mountedV on said insulated flexible members intermediate said battery cells, and means carried by said removable terminal head for holding said cells and ring members incircuit with said terminal heads when said removable head is closed.

2. An electro-galvanic generator, 4comprising an open casing provided with terminal heads and longitudinally extending metallic side'plates one of which is provided with insulated plug openings, a series of battery -cells mounted in said casing between said heads and communicating with said plug openings, connecting pins adapted to beinserted in said plug openings and betweenadjacent battery cells, and a spring Contact member carried by one of said heads and adapted to holdsaid cells in circuit with said heads.

3. In an electro-galvanic generator, an

open battery casing provided with a 'stationaryterminal head and contact member, a series of battery cells removably mounted thereinv and connected to each other by means of insulated cord members and conducting` ring members mounted on said cord members between said cells, and a removable head member provided with a spring contact adapted to hold said cells and contact members in operative relation to each other.

4. An elec'tro-galvanic generator, comprising an open casing provided at opposite ends with suitable terminal heads, one ot' which is removable and provided .with a spring Contact member, a series of battery cells removably mounted in said casing between said lterminal heads, insulated cord members extending` through said battery cells and provided with conducting ring members interposed between said cells, and

means for securing said removable terminalhead in closed position, whereby said cells and rin .members are held in circuit with said hea s by the tension of said spring contact member.

l 5. In an electro-galvanic generator, a casing provided with a statlonary terminal head and contact member vand metallic side plates one of which is provided with intermediate plug .openings and the other of which terminates-in a movable catch, a series of battery cells, insulated flexible members extending through said battery cells, metallic conduit members movably mounted on said insulated flexible members and interposed between said battery cells, and a removable head or end member adapted to be engaged by said movable catch and prol 100 vided with a spring contact member adapted to hold said battery cells and conducting members in circuit with said stationary contact member.

In testimony whereof I have aflixcd my 106 signature in presence of two witnesses.
